Abstract:This study aims to analyze the effect of Quick Ratio (QR), Debt to Asset Ratio (DAR), and Return on Assets (ROA) on firm value as measured by Price to Book Value (PBV) in consumer non-cyclical sector companies listed on…
the Indonesia Stock Exchange during the 2021–2024 period. The consumer non-cyclical sector was selected because it consists of companies producing essential goods with relatively stable demand, making it an important sector in the national economy. This research employed a quantitative approach using secondary data obtained from the annual financial statements of companies listed on the Indonesia Stock Exchange. The sampling technique used purposive sampling, resulting in 196 observations. Data analysis was conducted using multiple linear regression analysis with SPSS software, preceded by classical assumption tests including normality, multicollinearity, heteroscedasticity, and autocorrelation tests. The results show that partially, Quick Ratio has no significant effect on firm value, indicating that short-term liquidity is not the main consideration for investors in assessing company value. Debt to Asset Ratio also has no significant effect on firm value, meaning that the level of debt dependence does not directly determine market valuation. Meanwhile, Return on Assets has a positive and significant effect on firm value, indicating that profitability is the main factor influencing investor confidence and market value. Simultaneously, Quick Ratio, Debt to Asset Ratio, and Return on Assets have a significant effect on firm value. The coefficient of determination (R²) value of 0.510 indicates that 51.0% of firm value variation can be explained by the three independent variables, while the remaining 49.0% is explained by other factors outside this study.

pital structure was measured using Debt to Asset Ratio (DAR) and Debt to Equity Ratio (DER), firm value was proxied by Price to Book Value (PBV), while profitability was measured using Return on Assets (ROA). This research applied a quantitative approach using secondary data obtained from annual financial reports. The sample consisted of 154 observations selected through purposive sampling. Data analysis was conducted using multiple linear regression and Moderated Regression Analysis (MRA) with SPSS software. The results show that DAR has a positive and significant effect on firm value, while DER has a negative but insignificant effect on firm value. Simultaneously, DAR and DER significantly affect firm value. Furthermore, profitability (ROA) is proven to strengthen the relationship between DAR and firm value as well as between DER and firm value. These findings indicate that an optimal capital structure supported by strong profitability can increase firm value. Therefore, companies should maintain a balanced financing composition and improve profitability to enhance market valuation.
Abstract:This paper presents the design and performance evaluation of a high-voltage direct current (DC) generator based on the Cockcroft–Walton (CW) voltage multiplier for laboratory-scale applications in electrical engineering.…
g. Conventional high-voltage generation methods often involve bulky transformers and complex circuitry, making them less suitable for compact and cost-effective laboratory use. To address these limitations, a modular CW-based system is proposed, integrating a high-frequency input source with an optimized diode-capacitor ladder network. The proposed system is designed to achieve high DC voltage output in the kilovolt range while maintaining acceptable levels of ripple and efficiency. Experimental results show that the system can achieve up to 86% of the theoretical output voltage under no-load conditions, with an efficiency of around 70.8%. Furthermore, the ripple voltage of the generated output voltage is very small, demonstrating stable performance suitable for laboratory applications. The proposed design offers a compact, cost-effective, and reliable solution for high-voltage DC generation, making it highly suitable for educational and low-power applications.

The results indicate that service quality has a positive and significant effect on consumer purchase decisions. Furthermore, consumer satisfaction also significantly influences purchase decisions. Simultaneously, service quality and consumer satisfaction significantly affect purchase decisions, indicating that higher perceived service performance leads to greater customer satisfaction and ultimately strengthens purchasing decisions.
Abstract:The rapid development of digital marketing has significantly transformed business strategies, particularly for Micro, Small, and Medium Enterprises (MSMEs). Instagram has evolved beyond a social networking platform into…
a strategic marketing tool equipped with analytical features such as Instagram Insight. This study aims to examine the effect of Instagram Insight utilization on consumer purchase decisions at Rumah Madu, an MSME operating in Bandar Lampung, Indonesia.
This research adopts a quantitative approach using a survey method. Data were collected from 92 respondents through structured questionnaires and analyzed using SPSS version 27. The independent variable is the utilization of Instagram Insight, measured through three dimensions: follower demographic analysis, follower active time analysis, and content performance analysis. The dependent variable is consumer purchase decision. Statistical analysis includes validity and reliability testing, classical assumption tests (normality, multicollinearity, and heteroscedasticity), simple linear regression, t-test, F-test, and coefficient of determination (R²).
The results suggest that Instagram Insight functions primarily as an internal strategic evaluation tool rather than a direct determinant of consumer purchasing behavior. This study contributes to the digital marketing literature by highlighting the gap between analytic tool utilization and actual consumer conversion in MSMEs. Practical implications emphasize the need for better data interpretation skills and integrated marketing strategies beyond analytics usage alone.

Abstract:This study aims to evaluate the implementation of Islamic Religious Education (Pendidikan Agama Islam/PAI) learning in strengthening students’ religious moderation at SMP Islam Terpadu Bangkinang. Religious moderation is…
is conceptualized as a religious attitude that emphasizes balance, tolerance, justice, and respect for diversity, which are essential values in maintaining social harmony within pluralistic societies. In the Indonesian educational context, Islamic Religious Education plays a strategic role not only in developing students’ religious knowledge but also in shaping moderate religious attitudes that prevent intolerance and extremism. Therefore, systematic evaluation of PAI learning is crucial to ensure that religious moderation values are effectively internalized by students.
This study employs a qualitative approach with an evaluative research design to comprehensively examine how religious moderation values are integrated into PAI learning. The evaluation focuses on three main aspects: learning planning, learning implementation, and learning evaluation. Data were collected through classroom observations, in-depth interviews with Islamic Religious Education teachers and students, and documentation analysis of learning instruments such as lesson plans, syllabi, and assessment tools. These data collection techniques were employed to obtain an in-depth understanding of instructional practices, teacher–student interactions, and assessment strategies related to the cultivation of religious moderation values. Data analysis was conducted using an interactive model involving data reduction, data display, and conclusion drawing to ensure systematic and credible findings.
The findings reveal that PAI learning at SMP Islam Terpadu Bangkinang has integrated religious moderation values into learning objectives and instructional planning. Teachers explicitly formulate learning goals that emphasize tolerance, balance, and mutual respect, while learning materials are contextualized to students’ social realities. During the learning implementation stage, teachers apply dialogical and participatory teaching methods, such as discussions and case-based learning, to encourage students to critically reflect on religious issues and social diversity. These approaches provide students with opportunities to understand differing perspectives and develop moderate religious attitudes in a reflective and respectful manner.
However, the study also identifies several challenges in the implementation of religious moderation-based learning. The use of contextual and innovative instructional methods remains limited, and learning activities tend to rely on conventional approaches. Moreover, the evaluation of religious moderation attitudes has not yet been conducted systematically. Assessment instruments primarily focus on cognitive achievement, while affective and attitudinal dimensions—such as tolerance, openness, and balanced religious behavior—are not comprehensively measured using structured indicators or rubrics. This limitation affects the accuracy of evaluating students’ overall development of religious moderation.
This study concludes that continuous and systematic evaluation of Islamic Religious Education learning is essential to enhance the effectiveness of strengthening religious moderation among students. The development of more comprehensive, contextual, and sustainable assessment instruments is necessary to holistically measure students’ cognitive, affective, and behavioral dimensions. In addition, the adoption of more dynamic and participatory instructional strategies is recommended to support deeper internalization of religious moderation values. The findings of this study contribute to the discourse on Islamic education and religious moderation by providing empirical insights into evaluative practices at the secondary school level and offering practical implications for improving PAI learning in pluralistic educational settings.
Abstract:This study aims to develop a technically compliant and economically feasible design for a Restricted Security Area (RSA) perimeter fence surrounding Substation 7, the Chiller facility, and the Ground Water Tank (GWT) at…
Kertajati International Airport. These facilities constitute critical operational infrastructure supporting electricity distribution, terminal cooling systems, and water supply, including fire suppression reserves. Field observations identified the absence of a regulation-compliant perimeter protection system, exposing the utility cluster to unauthorized access and operational risk. The research employed a quantitative descriptive–analytical approach integrating field measurement, engineering design modeling, volume computation, and cost estimation based on the 2024 Majalengka Regional Standard Unit Price. Technical evaluation referred to national aviation security regulations and ICAO Annex 17 principles. A BRC (British Reinforced Concrete) fence system with a total height of 3.20 meters (2.40 m fence body and 0.80 m concertina wire) was proposed. The structural configuration includes reinforced concrete isolated footings, tie beams (sloof), and a bottom plinth beam to ensure lateral stability and anti-climb resistance. The total perimeter length of 313.74 meters ensures complete enclosure of the critical facilities. The estimated total project cost amounts to IDR 509,553,000.00, including VAT. The results demonstrate that the proposed design is structurally reliable, regulation-compliant, and economically justified within a risk mitigation framework. The study contributes a replicable engineering and financial planning model for strengthening airport critical infrastructure protection and enhancing long-term operational resilience.
